But in the idea of entropic gravity \u2014 as well as some other scenarios (like qbits) \u2014 gravitation or even space and time themselves might emerge from other entities in a similar fashion. There are well-known, close relationships between the equations that govern thermodynamics and the ones that govern gravitation. It\u2019s known that the laws of thermodynamics emerge from the more fundamental field of statistical mechanics, but is there something out there more fundamental from which gravity emerges? That\u2019s the idea of entropic gravity.\u201d<\/p>\n<p>Entropic gravity, also known as emergent gravity, is a theory in modern physics that describes gravity as an entropic force\u2014a force with macro-scale homogeneity but which is subject to quantum-level disorder\u2014and not a fundamental interaction. The theory, based on string theory, black hole physics, and quantum information theory, describes gravity as an emergent phenomenon that springs from the quantum entanglement of small bits of spacetime information. As such, entropic gravity is said to abide by the second law of thermodynamics under which the entropy of a physical system tends to increase over time.<\/p>\n<p><!-- Link: <a href=\"https:\/\/www.forbes.com\/sites\/startswithabang\/2017\/10\/04\/are-space-time-and-gravity-all-just-illusions\/#e87bbd241cf3\">https:\/\/www.forbes.com\/sites\/startswithabang\/2017\/10\/04\/are-...7bbd241cf3<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pioneered by Erik Verlinde, the idea is that gravity emerges from a more fundamental phenomenon in the Universe, and that phenomenon is entropy. \u201cSound waves emerge from molecular interactions; atoms emerge from quarks, gluons and electrons and the strong and electromagnetic interactions; planetary systems emerge from gravitation in General Relativity.
